Product Description:

The MDD093B-N-040-N2M-130GR1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and supplied in the MDD Synchronous Motors series. Built for use with digital drive controllers, it delivers closed-loop rotary motion in automated machinery that requires accurate positioning and repeatable speed control. This arrangement allows the connected drive to correct load changes quickly during indexing, feeding, and other point-to-point motion tasks. The motor uses the 093 frame size and B length code in a standard housing, which helps it fit common machine envelopes in this product line. It is dynamically balanced to the standard grade, so vibration remains predictable during continuous operation and frequent axis reversals.

At standstill, the motor can generate a continuous torque of 14.5 Nm, allowing loaded axes to maintain force without excessive thermal stress. During operation, it reaches a nominal speed of 4000 rpm, which supports fast travel rates when the drive is matched to the motor's electrical characteristics. The integrated blocking brake provides 11 Nm of holding torque, helping prevent axis drift when power is removed. A shaft seal is fitted at the output end to help keep contamination away from the bearing area. Electrical power and feedback signals are routed through a molded connector, which keeps the connection point compact and supports orderly cable routing. The brake supports static holding, while running torque remains controlled by the drive during normal motion.

A centering shoulder of 130 mm locates the flange accurately against the machine interface for repeatable mounting alignment. Position data is supplied by an integrated multi-turn absolute encoder, and the drive processes that signal through digital servo feedback (DSF) for precise speed and position control. Because the encoder is absolute and multi-turn, the controller can retain shaft position information across multiple revolutions after power returns. Cables exit on the right side, which suits installations that need that connection orientation. The motor uses a plain shaft at the drive end, and the design omits a side B shaft extension. This layout leaves only the primary shaft end available for coupling and keeps the opposite side clear for the brake and feedback assembly.
